  • Patent number: 8246535
    Abstract: A bending instrument for an endoscope which is used when a fiberscope is inserted into a gastrostomy catheter. The bending instrument comprises a sheath which covers a fiberscope shaft of the fiberscope, and a bending member which allows the fiberscope shaft to bend together with the sheath. A light-transmissive window part is formed at the tip end of the sheath. Furthermore, the bending member comprises a fixed part which is attached to the tip end outer periphery of the sheath, a sliding part which is slidably attached further to the base end side of the sheath than the fixed part and which engages with a cylindrical engagement part of the gastrostomy catheter so as not to be able to go past an intra-stomach fixed part, and a linear linking part which links the fixed part and the sliding part.

  • Publication number: 20090171153
    Abstract: An insertion assisting tool when inserting an endoscope into the gastric fistula catheter that has been inserted in the fistula formed in the patient's body comprises a cylindrical body that can be engaged with a gastric fistula catheter wherein an endoscope can be inserted through a valve press member and a sealing member. The valve press member can be installed detachably by screwing the screw threads with the edge portion at an opposite side of the portion engaged with the gastric fistula catheter in the cylindrical body, and is formed in a cap form having a hole portion in the sealing portion. The sealing member seals the space between the cylindrical body and the endoscope when it is pressed against the endoscope set at the space between the end portion of the cylindrical body and the valve press member.

  • Patent number: 7468058
    Abstract: A suction fluid collector includes a transparent reservoir made of a resilient material with an upper opening positioned on one side of a flexible suction bag with at least one transparent side. A plate part made of a resilient material is positioned on another side of the suction bag opposite said reservoir. An urging means arranged between the reservoir and the plate part provides a force tending to expand a gap between the reservoir and the plate part. A suction tube is positioned partially inside the reservoir and extends through the suction bag.
